Set, be typically set at 0.1 to 3mm scope.
On the one hand, the deformation pipe portion 31c, as shown in figure 3, it is preferred that forming screw thread or concavo-convex or wrinkle form in outer surface
Shape, thus, can be prevented when being deformed because of the thermal expansion of the flow distribution plate 10 damage.
As illustrated, the nozzle assembled portion 31d is Intercalation in forming the setting groove in the upper end of the nozzle 20
23 composition.Now, the setting groove 23 is connected with resin channels 21, with the diameter expanded to resin channels 21, the spray
Mouth assembled portion 31d is assembled in the setting groove 23 to be forcibly inserted into mode.
Preferably, the nozzle assembled portion 31d is mutually assembled with the setting groove 23 with section-differential insert structure.
Reference picture 2 illustrates the hot-fluid for possessing thermal expansion compensator according to one embodiment of the invention constituted as described above
The effect of duct device, in the state of not occurring thermal expansion shown in the left hand view A such as Fig. 2, the He of resin stream 11 of flow distribution plate 10
The resin channels 21 of nozzle 29 and the resin interface channel 31a of thermal deformation seal cartridge 31 remain configured to the shape on a straight line
State.
In this case, if the flow distribution plate 10 produces thermal expansion by heating wire continuous heating, such as Fig. 2 right part of flg
Shown in B, on the basis of the nozzle 20, the resin stream 11 of flow distribution plate 10 is conjugated towards side.
Now, the thermal deformation seal cartridge 31 of the thermal expansion compensator 30 of the present invention is constituted, as illustrated, corresponding deformation pipe
Portion 31c is deformed according to the thermal expansion deformation amount of the flow distribution plate 10, thus, keep in the same old way the nozzle 20 position it is same
When, compensate the displacement produced by the thermal expansion of the flow distribution plate 10.
I.e. described thermal deformation seal cartridge 31 can stably connect the resin stream 11 that keeps the flow distribution plate 10 and described
The resin channels 21 of nozzle 20, so as to prevent gap, and can prevent resin from revealing.
Fig. 3 is for illustrating cutting for the other embodiment of the hot-runner device for possessing thermal expansion compensator according to the present invention
